No kiddies, I'm not talking about the man in the moth-eaten trench coat, who wants you to go back to his house so he can give you sweets. I'm talking fun strangers, unusual strangers, people who you can learn from!
I have all sorts of issues, especially when it comes to being confident and speaking to people. But every so often, somebody just sort of turns up at an unexpected moment, and they captivate you with stories and adventures, and you realise that you aren't alone in this big old world. There are others that get you.
A few weeks ago, for instance, me and my cousin went out for a few drinks, and met a wonderful, well-spoken chap (who can be followed on Twitter here: @mister_meredith) who just so happened to share many of our interests. He had even met several (read: lots!) of major 'Doctor Who' personalities. He's also a top-rate caberet performer, and unafraid to speak his mind!
And there's Twitter. Out of my 800-odd followers, I know about 5 people in 'the real world' (including my partner in geekiness, the incomparable @Sonic_Bionic). The rest are quite literally strangers, who sprang out of nowhere on this social networking site, and became friends extremely quickly. Fascinating people from all over the world, who have the same loves and hates, and who have seen things I can only dream of. They know who they are (many can be traced by visiting the list of websites on the left-hand side of the page), and they have given me a great deal of pleasure.
So, when a chap turns out of the blue telling you he once knew Sir Isaac Newton, don't run away in terror. Listen to him - you might just wander into a whole new world...
